About

Hey, I'm Roger Hosto.

I’m a database platform engineer, systems architect, and technology leader with over two decades of experience designing, scaling, and optimizing the infrastructure that keeps complex digital systems running.

By day, I'm the Director of Database Platform Engineering at Teladoc Health, where I lead engineering teams and manage high-availability database architectures. My career has been built around solving tough engineering problems—whether that means architecting resilient data pipelines, scaling relational and document databases across cloud environments, or integrating modern AI and machine learning workloads into enterprise platforms.

Beyond the Server Room

When I’m not deep in query execution plans or infrastructure configuration, you'll usually find me building or tinkering with something tangible. I like to apply the same structured, systematic approach I use in software development to my hobbies:

• Homebrewing & Fermentation: I'm a passionate homebrewer currently studying for the Beer Judge Certification Program (BJCP) and Cicerone certifications. I love experimenting with recipe formulation, small-beer session techniques, and traditional styles, alongside other home-fermented crafts like sourdough and preserves.
• Building & Creating: Whether it's coding software projects (like my web app BeerSchooner or developer CLI tools), experimenting with local AI inference runtimes, or designing 2D games in Defold, I always have a side project on the workbench.
• Music & Outdoors: I play a 3-string guitar tuned to Open G, transcribe classic rock tablature, and enjoy spending time outdoors fishing, and managing property.

What You'll Find on This Blog

This site is my digital workshop—a place where I share insights, notes, and deep dives into the topics I spend my time thinking about. You'll find articles touching on:

• Database Engineering & Architecture: Practical guides, performance tuning tips, and architectural patterns for PostgreSQL, MySQL, SQL Server, and MongoDB.
• AI & Software Development: Notes on building local and production AI agents, automation tooling, and modern software engineering practices.
• Craft Beer & Fermentation: Technical deep dives into brewing science, style guidelines, and recipe design.
